Aeronautics and Aerospace Industry

From the aeronauts of the early republic to the jets, missiles, and rockets of the Cold War era, the growth and development of the aeronautical and aerospace industry in the Philadelphia region has exemplified a gradual shift from amateur pursuits to a more formalized industry and infrastructure. Across several centuries, the city and surrounding suburbs ⇒ Read More

Airports

Commercial aviation grew dramatically in the United States in the twentieth century, and a number of airports in the Philadelphia area grew to become regional centers of the industry. There was nothing assured or inevitable about this growth, however. It depended on the efforts of local political leaders, investments by the aviation companies, and state ⇒ Read More

American Friends Service Committee

The American Friends Service Committee (AFSC), co-recipient of the Nobel Peace Prize and coiner of the phrase “speak truth to power,” was founded in Philadelphia by members of the Religious Society of Friends (Quakers) in Spring 1917, shortly after the United States declared war on Germany on April 6. Over the following century, AFSC embodied ⇒ Read More

Armories

Armories served as military training and recruiting sites, arms depots, headquarters, and social clubs for the nation’s citizen-soldiers. Early armories in Philadelphia were simply rented spaces in commercial buildings. After the Civil War, permanent structures for the exclusive use of the Pennsylvania National Guard supplanted these ad hoc armories as business interests responded to labor ⇒ Read More

Arsenals

For much of the nation’s history Philadelphia held a preeminent position as the provider of logistical support to the U.S. Army, and federal arsenals played a considerable role in the economic life of the city. The Schuylkill Arsenal and Frankford Arsenal were, respectively, the largest manufacturers of uniforms and small-arms ammunition in the country, often ⇒ Read More

Artisans

As skilled laborers who hand-crafted their goods on a per-customer basis, artisans played a central role in the formation of Philadelphia’s prerevolutionary economy: producing essential goods and services and providing social stability within households composed not just of immediate family but also of journeymen and apprentices. American independence brought artisans new economic opportunities as the ⇒ Read More

British Occupation of Philadelphia

On September 26, 1777, the British army marched into Philadelphia, beginning an occupation that lasted until the following spring. Its arrival led patriots to flee and Loyalists to rejoice, although wartime shortages soon led to suffering for those who remained in the city. The occupation, however, led to no concrete gains, and the British abandoned ⇒ Read More

Civil Defense

Because of Greater Philadelphia’s position as a political, cultural, and economic hub, the region’s residents have often found their daily lives deeply affected by times of national crisis. Civil defense, generally defined as local voluntary programs designed to protect civilian life and property during times of conflict, has taken many forms: militia, home defense, civilian defense, ⇒ Read More

The Mid-Atlantic gunpowder industry flourished in the nineteenth century along the Brandywine River in Delaware and spread into Pennsylvania, New Jersey, and other states.

Helicopters

From barns and airfields throughout the Delaware Valley, during the twentieth century innovative individuals and local companies made greater Philadelphia the nation’s cradle of rotary-wing aviation.  They successfully launched autogiros, gyroplanes, and helicopters, and the Boeing Company paired with Bell Helicopters in Buffalo, New York, to produce the world’s first production tilt-rotor aircraft, the V-22 ⇒ Read More

Korean War

Although active hostilities during the Korean War lasted for little more than three years (1950-53), the conflict had a lasting impact on the Philadelphia area.

Lafayette’s Tour

When the Marquis de Lafayette (1757-1834), a French hero of the American Revolution, returned to the United States in 1824-25, Philadelphians joined in a wave of nationwide affection for the nobleman who had volunteered for service in the Continental Army at the age of 19.

Military Bases

For centuries, the American military valued Philadelphia because of its size, manufacturing capability, and location.

Closures, conversely, led to ⇒ Read More

Militia

As the social and political center of colonial Pennsylvania, Philadelphia and the surrounding region served as a microcosm for the complex and often convoluted history of the colonial and early national militia.

National Guard

The roots of the National Guard can be traced to Philadelphia and congressional action during the city’s decade as the nation’s capital.

National Parks

National parks figure prominently in Greater Philadelphia’s cultural, economic, and natural landscapes.  Morristown (1933), Independence (1948), Valley Forge (1976), and First State (2015) National Historical Parks all preserve and provide access to sites associated with the American Revolution and early American history. Together they welcome nearly six million visitors each year and create more than ⇒ Read More

Native American-Pennsylvania Relations 1681-1753

Indian-brokered alliances more than Quaker pacifism anchored the “long peace” in the decades that followed Pennsylvania’s founding in 1681.

Native American-Pennsylvania Relations, 1754-89

Relations between Pennsylvania’s Native American and European peoples underwent cataclysmic change during the second half of the eighteenth century.

Pacific World (Connections and Impact)

Historians have often situated Philadelphia in three geographic contexts: on the western edge of the “Atlantic World” during the colonial era, as an eastern metropole for hinterlands and the receding frontier to the west, and in the mid-Atlantic region between the North and South of the United States. These geographic frames all make sense, given ⇒ Read More

Philadelphia (Warship)

Inspired by patriotic fervor during the Quasi-War with France, the people of Philadelphia raised money in one week during June 1798 to build the USS Philadelphia to help increase American naval power to protect commerce.

Philadelphia Navy Yard

The history of the Philadelphia Navy Yard has been one of constant struggle, repeatedly staring down imminent closure only to be saved at the last second by stalwart local politicians or a timely military conflict.

Point Breeze (Bonaparte Estate)

Joseph Bonaparte’s Point Breeze estate was one of the finest country houses in the Delaware Valley.

Privateering

As one of the largest British ports in North America, during the eighteenth century Philadelphia held a prominent place in privateering, the practice of privately financed warships attacking enemy shipping during wartime.

In addition, the war ⇒ Read More

Trails (Indian)

In the Philadelphia region prior to European settlement and during the colonial period, the Lenapes and other Indians used their knowledge of the landscape to engineer the most efficient routes through forests, mountains, and often shallow, treacherous waterways.

Treaty Negotiations with Native Americans

From the arrival of Europeans in the seventeenth century through the era of the early republic, treaties were an important tool in diplomacy between native nations and colonial Pennsylvania and later the nascent federal government.

Trenton and Princeton Campaign (Washington’s Crossing)

One of the most significant events in the Revolutionary War was the Continental Army’s December 25, 1776, crossing of the Delaware River, led by General George Washington (1732-99), which preceded three crucial American victories—two at Trenton and one at Princeton, New Jersey—that reignited the virtually extinguished Patriot cause.  Immortalized in the famous 1851 painting by ⇒ Read More
